Sun Halo over Oz

During a walk at The Nobbies on Phillip Island in the South of Australia I was treated to a rare phenomenon that had people turning their heads to the sky: a Sun Halo.

The light refraction causing this optical phenomenon happens due to ice crystals in a thin veil of cirrostratus clouds high in the atmosphere (as opposed to low level raindrops which create rainbows when interacting with sunlight).
